Samsung QN90B vs QN900B: Picture Quality​

With impressive peak brightness, the Samsung QN90B is strong enough to overcome glare to deliver excellent images, even in rooms with lots of ambient light or bright sunlight. In some large bright scenes, the TV's automatic brightness limiter will reduce its brightness.

The TV's native contrast ratio isn't too high, due to Samsung's addition of a wide viewing angle layer to increase the viewing angle of the screen. But it has excellent local dimming, and when you set it to high, you can get a good contrast ratio. Although halos can appear around some bright spots in dark scenes, it's not very noticeable. It's great for watching movies with dark scenes. Note that the QN90B has poor local dimming performance in game mode.

The Samsung QN900B has a very good high peak brightness and is bright enough to resist glare in well-lit rooms. Likewise, it has an automatic brightness limiter that will reduce the brightness of large bright scenes.

It has a low native contrast ratio, which, like the QN90B, is due to Samsung's wide viewing angle layer. The local dimming feature will boost contrast and produce uniform blacks. But some bright objects will produce noticeable halos around them, which will distract your attention.

The viewing angle of the Samsung QN900B is not bad, but not as good as the QN90B, and the image can fade a bit when viewed off-screen. Of course, the viewing angle of the OLED screen is better than LCD TV. You can refer to Samsung QN90B vs LG G1.

The 8K resolution provides more detail, but it really depends on the quality of the content. With the lack of native 8K content available now, giving up cheaper 4K TVs in favor of 8K TVs may be a less cost-effective option.

Samsung QN90B vs QN900B: Design​

The Samsung QN90B has a sleek and elegant design with very thin bezels and a black metal stand. The stand is narrow and can be easily placed on narrow desktops. The stand is small enough that larger screens will wobble a bit on it. It raises the TV and you can place most of the soundbar in front of the TV screen.

As an LCD TV, the QN90B's panel is thin enough and doesn't stick out in any way. You can wall mount it and the TV can sit flush with the wall. The back of the TV is made of high-quality plastic with channels set up for cable management.

The Samsung QN900B continues to feature a minimalist design, with a bezel that's thin enough that you'll hardly notice it from the front. So you won't be easily distracted while watching TV programs. The TV has a small, centered stand that fits on a smaller table. The plastic panel on the back of the TV has a premium pattern and the panel is very thin, making it ideal for wall mounting. the QN900B features the One Connect box, so you can access and manage inputs more easily.

Both TVs are equipped with the Samsung 2022 version of Tizen OS 6.5. The new version of the system has a new user interface made to fill the entire screen.

Samsung QN90B vs QN900B: Summary​

Overall, both the Samsung QN90B and Samsung QN900B are comprehensive TVs for multiple uses, with the biggest difference being that the QN90B supports 4K resolution, while the QN900B is an 8K TV.

However, considering the actual usage and the current lack of native 8K content, 8K TVs are not that attractive for most people, not to mention their expensive price tag.

Therefore, for everyday use, I would recommend the Samsung QN90B, which offers satisfactory contrast, brightness, excellent gaming performance, and a good viewing angle.
